2022 State of the EU ETS Report
Key Takeaways

• This report marks the beginning of Phase 4 of the European Union’s Emissions Trading System (EU ETS),
  which started in 2021 and is marked by debates in line with a new climate ambition target. The European
  Climate Law is providing a new reality to become net zero by 2050. However, the EU ETS debate may
  not be as visible as in the past since other elements of the Fit for 55 package such as the CBAM, have
  become the focus of attention. ERCST would argue that the focus must remain on the EU ETS.
• The year 2021 was not only marked by a period of completing secondary legislation coming from the
  revision of the EU ETS Directive in 2018 but has also brought a proposal from the Commission to revise
  the current framework. The new rules are expected to apply from 2023, pending the success or failure
  of the upcoming negotiation process between the European Parliament and Council.
• While some elements are still at stake, Phase 4 of the EU ETS is the first one without UK installations.
  The need to achieve a worldwide climate compromise and the recent discussions in international forums
  (i.e., COP 26) has showed the need to further envisage the role of the EU ETS and international carbon
  markets, aiming for potential links under Article 6 of the Paris Agreement.
• In 2021, ahead of the Commission proposal to revise the EU ETS Directive, presented in July 2021, the
  stakeholder community looked optimistic about the possibilities of the EU ETS embracing the climate
  goal. Nevertheless, the annual market sentiment survey shows some questioning of the role of the EU
  ETS in some areas. Still, stakeholders consider the EU ETS as the pillar of the EU climate policy and as
  one of the best, if not the best, of the instruments to drive decarbonisation.
• Following the previous year’s reports, this report shows the dynamics of emissions in different sectors.
  Estimates based on preliminary data indicate a 9.1% increase of total emissions in 2021 compared to
  2020. Still, the dip in emissions caused by lower economic activity due to the COVID-19 crisis in 2020
  had not yet been overcome in 2021.
• We cannot disregard that last year the EU was impacted by an unprecedent increase in energy prices.
  The discussion has also been revolved around the relationship between the energy and the carbon
  market and the increased high volatility of carbon prices. The role of speculators and the different
  treatment of compliance entitles, for which the EU ETS is a compromise to achieve efficient
  decarbonisation rather than an opportunity to obtain profits, has raised questions about the current
  provisions to address excessive market price fluctuations, and the need to include these considerations
  in the EU ETS review.
• Finally, some see this as the time to start exploring the role of the EU ETS post 2030.

                                                                                                        1
1. Background
This “State of the EU ETS” Report is an independent effort which is not intended to duplicate or replace
mandated work undertaken by the Commission. It focuses on identifying issues and assessing the
performance of the EU ETS at the time when the report is produced.
This report is intended as a “snapshot”, providing policymakers and stakeholders with an overview of how
the EU ETS is doing by April of each year, based on previous year data. Within the constraints posed by the
availability of publicly accessible data, the Report tries to assess the question of whether the EU ETS is “fit
for purpose”.
As background, following the completion of the review of the EU ETS in early 20181 many stakeholders
assumed that the EU ETS was “fit for purpose” until 2030. However, much has happened since then. The
European Green Deal (EGD)2 and the endorsement of the climate neutrality objective by the European
Council3 in late 2019 has put us on a very different path. Subsequently, the European Climate Law was
passed, which provides the legal basis for the EU’s economy and society to reduce (net) Greenhouse Gas
(GHG) emissions by 55% (vs 1990) by 2030 and achieve (net) climate neutrality by 2050.
Today, we are in the middle of a new review process, not only for the EU ETS, but for all climate and energy
policies as part of the “Fit for 55” package, which was adopted by the Commission on July 14th, 20214. The
European Parliament and Council are currently defining their own positions, which are expected to be
adopted before the summer. The negotiations between the EU institutions, so-called “trilogues”5, on the
final form of the revised EU ETS are expected to begin in September under the Czech Republic Presidency
of the EU Council.
The aim is to have the revised EU ETS in place in 2023, the year of the first global stocktake of the Paris
Agreement (GST). The global stocktake is a process envisioned in Article 14 of the Agreement and aims to
assess the collective progress of countries towards achieving the goals set out in the Paris Agreement6.
Article 30(3) of the EU ETS Directive mandates the Commission to report to the European Parliament and
to the Council in the context of each global stocktake agreed under the Paris Agreement about the need for
additional Union policies and measures to achieve the full implementation of the Paris Agreement by
Member States7.
As part of the Fit for 55 Package, the Commission set out a new target for the sectors covered by the EU
ETS: reducing emissions by 61% (vs 2005 levels) by 2030, compared to the previous target of 43%. To
achieve this new target, a tightening of current ETS parameters is envisioned, including a lowering of the
cap and a reduction in the provision of free allowances. In addition to these measures, the Commission has
proposed the so-called "ETS 2”, which would introduce an ETS for road transport and buildings starting in
2026. This proposal has led to a heated debate in the European Parliament and Council where opinions

continue to be divided. Chapter 4 will provide a detailed overview of the different elements of the “Fit for
55” package as they apply to the EU ETS.
Moreover, in 2020 the measures put in place to address COVID-19 and the developments in Ukraine have
impacted the EU ETS and Europe has experienced a dramatic increase in both carbon and energy prices.
The Commission published the ‘Energy Prices Toolbox’ in October8 outlining available measures to address
prices. This will be discussed in Chapter 6.
2021 is also a year marked by the 26th UN Climate Change Conference of the Parties (COP26) in Glasgow,
which was postponed from November 2020 to November 2021 due to the Covid-19 pandemic. The results
of the COP26 negotiations emphasized continued global agreement to keep global warming as close as
possible to no more than 1.5°C above pre-industrial levels, as well as an agreement on the Article 6
Rulebook. This could sway the EU to take a more internationalist approach for the EU ETS.
Finally, the EU ETS does not exist in a vacuum. It should not be compared to an ideal world, but to real
options that are available to address climate change.
The EU ETS and EU climate policy are put in place to decarbonize the EU while ensuring that the outcome
is a prosperous and industrial Europe. The EU ETS operates in a highly interconnected environment and is
affected by climate change and other policies at different levels: global, EU, EU Member State, and sub-
national jurisdictions. It must live with that reality and respond to it.

2. An EU ETS “fit for purpose”
To assess whether the EU ETS is “fit for purpose”, we first need to identify the parameters which measure
its success. Simply put, “what do we expect the EU ETS to deliver?”. Indicators have emerged gradually, as
experience is gained with these mechanisms, both in the EU, but also around the world. Experience from
other, non-carbon, markets may also provide benchmarks for success. Nevertheless, some of these
assessments will have a level of subjectivity and judgement (sometimes political) attached to them.
In this context, we need to remind ourselves that Article 1 of the EU ETS Directive9 outlines its broad
objectives:
        “This Directive establishes a scheme for greenhouse gas emission allowance trading within the
        Community in order to promote reductions of greenhouse gas emissions in a cost-effective and
        economically efficient manner. This Directive also provides for the reductions of greenhouse
        gas emissions to be increased so as to contribute to the levels of reductions that are considered
        scientifically necessary to avoid dangerous climate change.”
Some objectives are clearly enunciated and identified, while some stakeholders may see other objectives
as implicit. The direct deliverables assessed by this report include:
     1. Environmental delivery. Does it deliver against absolute environmental targets?
     2. Socio-economic delivery. Does it deliver macro-economic efficiency and cost effectiveness for
        compliance? Does it provide effective, and proportional, protection against the risk of carbon
        leakage? Is it a driver for change? Does it ensure a just transition?
     3. Market functioning. The ETS, which is a regulatory market, should only be the instrument of choice
        if it functions well and leads to good price discovery.
Over time, other deliverables or indicators have come to be “expected” or “understood”. Some have come
to equate the good functioning of the EU ETS, wrongfully in our view, with the delivery of a “right price”

which could incentivize certain technologies or approaches. This report will not judge the success or failure
of the EU ETS based on price levels. The EU ETS needs to be technologically neutral, and not an instrument
to increase prices and revenue.

One indicator not explicitly mentioned is the expectation that the EU ETS will contribute to a long-term
(competitive) advantage for Europe. This has become more explicit with the EGD, which was presented by
the Commission as Europe’s “New Growth Strategy”, aimed at transforming the EU into a fair and
prosperous society.
The main issue is perceived to be the magnitude and source of upfront investments that need to be made
in order to put Europe firmly on a new path of sustainable and inclusive growth, as well as the question of
how to manage the transition.
Some stakeholders see the EU ETS as a key instrument of economic and social engineering that will help
accelerate the transition to a low-carbon economy by:
    • Providing a price signal to accelerate economic transition, as well as change societal values,
        behaviour and systems;
    • Addressing the socio-economic impacts associated with the transition to a low-GHG economy;
    • Contributing to the creation of a market for low-carbon products.
Some of the objectives can be considered as being more explicit, as they are clearly captured in the EU ETS
Directive by the legislators. They encourage investments in low-carbon technologies, help address socio-
economic impacts, and facilitate a “Just Transition”.
For these objectives, the inputs are clear and KPIs can be developed, e.g., in terms of the amount of
investment leveraged; new jobs created; retraining of workers, etc. The others could be considered as being
less “mature” and transparent in the policy debate, and KPIs more difficult to develop.

Promote carbon pricing
The EU ETS has become a pioneer in promoting carbon markets as a tool for addressing climate change.
Many studies, including the Annual ICAP Status Report10 and the annual State and Trends of Carbon Pricing
report from the World Bank11, show that carbon pricing is spreading across the world. Some other actors,
for instance the International Monetary Fund (IMF), are calling for an international carbon price floor12. The
internationalization of the EU ETS, including in linking it with other markets, as well as the use of Article 6
of the Paris Agreement for offsets, need to be considered as part of the vision during the transition period.
The EU is using multiple approaches to promote the use of carbon markets around the world. Firstly,
through “leading by example” and persuasive climate diplomacy, resulting in other jurisdictions taking
inspiration from the EU ETS. Secondly, the EU is able to leverage climate ambition or the use of carbon
markets as a condition in free trade agreements or its accession process. Lastly, the EU can use a “stick”
approach in its interaction with other countries to persuade them to adopt more ambitious climate policies
and/or carbon pricing mechanisms. The proposed use of a Carbon Border Adjustment Mechanism (CBAM)
is a move in this direction.

3. Phase 3: a comprehensive analysis
3.1. The recovery Phase of the EU ETS
Phase 2 (2008-12) of the EU ETS was known for the low carbon prices it delivered. In particular, the 2009
European Union Allowances (EUA) price crash brought to light structural issues that prevented the EU ETS
from coping with economic shocks and from providing a good price discovery given the regulatory nature
of the EU ETS.
A series of reforms were implemented in Phase 3 (2012-2020) to make the EU ETS fit for delivering a price
signal that was aligned with the EU’s long-term emission reduction goal. The surplus of allowances
accumulated due to overlapping policies and the economic downturn was addressed through the
backloading of auctioned allowances, and the progressive reduction of free allocation.
In addition, a new mechanism – the Market Stability Reserve (MSR) – was implemented to improve the EU
ETS’ resilience to demand shocks. Finally, the revision of the EU ETS Directive for Phase 4, adopted in 2018,
set a new 2030 target aligned with the Paris Agreement. Subsequently, the announcement of the EGD
increased confidence in the EU’s climate ambition for 2050 and signalled the EU’s willingness to design the
EU ETS accordingly.

The combustion sector not only includes
electric utilities, but also combustion plants of other sectors where they exceed the 20 MW participation
threshold15. Emissions of other sectors in Figure 1 therefore correspond to process emissions only.

13 To reflect changes in scope between trading periods (i.e., addition of new countries and sectors except for aviation), the data was re-

treated to derive a time-series for stationary installations starting from 2005 consistent with the scope of the third trading period. See EEA’s
background note for details available at https://www.eea.europa.eu/data-and-maps/dashboards/emissions-trading-viewer-1 (accessed on
12 April 2022).
14 The information on the type of activity of the entities covered by the EU ETS is based on the EUTL classification (which differs from UNFCCC

nomenclature for GHG emission source categories or NACE codes).
15 The scope of the EU ETS includes all combustion installations exceeding 20 MW and all installations where activities listed in Annex I of the

ETS Directive are carried out (EU, 2003). The combustion sector therefore includes electricity production (up to 54% of installations according
to euets.info data) but also other economic activities using boilers, burners, turbines, heaters, furnaces, incinerators, calciners, kilns, ovens,
dryers, engines, fuel cells, chemical looping combustion units, flares, and thermal or catalytic post-combustion units falling over the 20 MW
participation threshold.

                                                                                                                                                                                                            5
Additionally, the potential mis-categorization of emissions in the EUTL data (e.g., combined heat and power
emissions not included in industrial sectors) is not accounted for here.
Over Phase 3, the rate of decrease of emissions turned out to be more than twice as high as the LRF, with
an average decrease of 5% per annum (6.4% in combustion, 1.3% in other stationary installations). The
largest annual decrease of emissions took place from 2019 to 2020 because of the impact of COVID-19 on
economic activity, with a decrease of 11% in stationary installations’ emissions. Furthermore, emissions
from aviation decreased by 63% as air travel almost halted during the pandemic.
Overall, several signs demonstrate the start of the decarbonization over Phase 3. The carbon intensity of
combustion plants decreased by about 30% from 2013 to 2019 due to an increased share of renewable
energy in the power mix and fuel switching opportunities.16 In other installations of most sectors, carbon
intensity improvements were modest but consistent over the period.17
One matter is important to note: most of the reductions in Phase 3 were achieved in the power sector, and
while the EU ETS played a guiding role, it is generally accepted that it was not the driving factor. this
decarbonization is largely due to other policies and measures as well as a significant level of subsidies
received by the power sector. This, coupled with the low carbon prices, made it possible for the power
sector to move aggressively away from fossil fuel generation.

mainly due to the power sector transition to
full auctioning. Regarding process emissions (i.e., stationary installations other than combustion), the
aggregate deficit experienced since 2017 was mainly driven by the refining of mineral oil, production of
coke, as well as cement and chemical industries to a smaller extent. On the other hand, metallurgy and
paper process installations had a positive allowance balance throughout Phase 3.
Differences in allowance balances can be explained by the data’s high level of aggregation and differences
in the origin of emissions between economic sectors, e.g., if metallurgy has a large share of combustion

                                                                                                              6
installations, the allowance balance of metallurgy’s process emissions would appear large by comparison
to a sector whose emissions mainly originate from process installations.
Table 1 provides a static overview of sectors’ allowance balances, but it does not account for allowance
banking. Banking gives the option to account holders to save unused emission allowances for use in future
trading periods. Indeed, since 2013, allowances delivered can be used in any further trading period,
according to Article 13 of Directive 2003/87/CE.
Table 2, therefore, tries to quantify the actual allowance deficit when considering banking. It results in the
number of emissions exceeding installations’ total allowance holdings, i.e., yearly free allocation plus the
accumulated bank, if any, which can be interpreted as the number of allowances purchased on the
secondary market. In aggregate, the banking flexibility enabled stationary installations of most sectors
except for combustion to keep a positive allowance balance during Phase 3. In other words, process
installations could have relied on the aggregate accumulated bank to cover emissions, without a need to
purchase allowances on the secondary market. By contrast, combustion installations, and process
installations of the refining and coke7 sectors would have had to purchase allowances in the market due to
a lack of reserves since 2013.

  The annual bank is calculated as the positive difference between annual free allocation and emissions, plus the bank of the preceding

allocation received.
Figure 3 also shows that, as a whole, the effective carbon cost has increased more than sevenfold from
2013 to 2020, due to the phase down of free allocation coupled with increasing EUA prices. This trend has
been mainly driven by the scarcity of allowances in aviation, combustion installations, and process
installations in the refining and coke sectors. Process emissions in other manufacturing sectors could have
been almost entirely covered by free allowances (Table 1), hence the effect of carbon cost is negligeable
for these sectors.

goes to the general budget of Member States.

In 2021, Member States reported on the type of support used domestically for the first time.21 In 2020,
most of the reported revenues were spent on direct support (Figure 5), i.e., on the installation of
technologies that reduce emissions. In particular the development of renewable energy to meet the EU’s
targets, measures to encourage a shift to low-emission and public forms of transport, and energy efficiency
measures were the main beneficiaries of auction revenues. Interestingly, around 60% of the EU ETS
revenues was spent in non-ETS sectors.

relevance).

                                                                                                                                   9
By looking at the numbers more closely (Figure 6), it is possible to identify some trends among Member
States on how they used auctioning revenues in 2020. Particularly countries from Northern and Southern
Europe used them mainly to develop renewable energy to meet the EU’s target, while Central and Eastern
European Member States gave preference to encouraging a shift to low-emission and public forms of
transport. Countries from Eastern Europe invested in energy efficiency measures. An important share goes
to other domestic GHG reduction measures, especially among some of the biggest countries in the EU, such
as Germany, France, and Italy, which use, respectively, 75%, 42% and 20% of these revenues for those
policies.

3.4. Resilience of the EU ETS
Phase 3 of the EU ETS succeeded in restoring the scarcity of allowances in the market, which, as expected,
impacted the carbon price. It was also the phase of a major structural change, the Market Stability Reserve
(MSR), implemented in 2019 to (i) address the existing surplus of allowances and (ii) improves the system’s
resilience to major shocks. The MSR operates by altering the total number of allowances in circulation
(TNAC) according to pre-defined rules and by cancelling allowances when the TNAC exceeds a specified
threshold.
There is little history to evaluate the impact of the MSR on environmental and economic outcomes of the
EU ETS, yet its implementation evidently coincided with a strong increase in EUA prices. The role played by
the MSR in the recent price rise is not clear, however. No correlation has yet been found22 between the
TNAC and EUA prices.23
Some, who equate high prices with success of the EU ETS, would argue that the MSR’s support function can
be perceived as a success as prices remained high during the COVID-19 pandemic. The recent escalation in
prices (+50% between October 2021 and February 2022) creates doubts about the success of the EU ETS to
incentive effective decarbonisation.
Several studies have raised concerns about the MSR’s ability to bring stability to the market. First, the MSR’s
action is based on past TNAC volumes, which has been criticized as being contrary to the forward-looking
nature of the EU ETS. For instance, the decision to bank allowances for hedging purposes can result in the
MSR cancelling allowances, further reinforcing allowance scarcity and triggering price spikes.24 Secondly,
the cancellation mechanism has been pointed out as a potential factor in creating short-term price volatility
as it creates uncertainty around the future cap on emissions.

4. Regulatory developments
4.1. EU developments
4.1.1. Secondary legislation for Phase 4 of the EU ETS
Having started in 2018, work on the secondary legislation to implement the provisions in Phase 4 of the EU
ETS has continued in 2021. Except for the exclusion of incoming flights from the UK from the scope of the
EU ETS, developments have been mainly focused on setting the conditions for the update of free allocation
for the 1st sub-period (2021-2025) of the EU ETS, following the submission of data by Member States. The
indicative timeline of secondary legislation is presented in Figure 7.

22 EU ETS: The Market Stability Reserve should focus on carbon prices, not allowance volumes. Energypost. June 16, 2020. S.Quemin & M.

Pahle.
23   Other factors such as hedging and speculation could have played an equally important role in driving prices.
24 The TNAC is computed based on the difference between past volumes of allowances freely allocated or sold (supply), and emissions plus
allowances in the MSR (demand). It therefore does not represent the balance of the market, which also depends on anticipation of future
prices and hedging behaviors.

                                                                                                                                    10

territory covered by the
Directive 2003/87/EC.
The NIMs included information on production activity, transfers of heat and gases, electricity production
and emissions at sub-installation level. The NIMs were used by the Commission to calculate the benchmark
values which are used to determine the level of free allocation.
On 12 March 2021, the Commission adopted the Implementing Regulation determining the revised
benchmark values for free allocation of emission allowances, for the period 2021 to 2025.26
On 31 May 2021, the Commission adopted its Decision on the Cross Sectoral Correction Factor (CSCF)27. The
CSCF adjusts the free allocation of emission allowances if demand from industry exceeds the free allocation
quota under the EU ETS Directive.
For each year in the allocation period from 2021 to 2025, the CSCF will be 100%, thus the CSCF will not
reduce the level of free allocation further.
The publication of the National Allocation Tables (NATs)28 on 29 June 2021 was the last stage of the
legislative process for the update of the benchmarks in the first subperiod of the EU ETS. Using the revised
benchmark values, the NATS determine the list of installations under the EU ETS eligible to receive free
allocation and the level of free allocation provided to them for each year in the period 2021-2025.

Finally, the last piece of EU ETS secondary legislation adopted in 2021 is the Delegated Regulation on the
exclusion of incoming flights from the United Kingdom from the scope of the EU ETS.29 It exempts departing
flights from the UK to the European Economic Area (EEA) based on Article 25 of the EU ETS Directive.30
No secondary legislation or modification of the Article 29a of the EU ETS Directive to address excessive price
fluctuations has taken place in 2021, this being a potential element to consider under the current energy
crisis and its impact on carbon prices.

4.1.2. Fit for 55
On July 14, 2021, as part of the Fit for 55 package, the Commission published its legislative proposal for the
MSR review.31 The European Climate Law32 sets the overall EU intermediary target of reducing GHG
emissions by 55% by 2030 (versus 1990 levels) to reach net zero by 2050.
In the case of the EU ETS, this will mean an increase from the current target of -43% to - 61% for EU ETS
installations by 2030 (versus 2005 levels). To reach this target, the Commission is moving from a Linear
Reduction Factor (LRF) of 2.2% to 4.2% from 2024 onward. In addition to this, the Commission proposes a
one-off removal of 117 million allowances (a so-called “rebase”) in 2024.
The increased target is also reflected in the proposed adjustment of the maximum benchmark update rate
from 1.6% to 2.5%, starting in 2026. The ETS revision has also launched a debate on the future of free
allocation, a tool which is currently used to address the risk of carbon leakage.
According to several projections, free allocation could run out by the end of this decade, meaning that the
CSCF may kick in. In the EGD, the Commission announced that, should differences in the levels of climate
ambition persist worldwide, it would propose a CBAM, to ensure that the price of imports more accurately
reflects their CO2 content. Consequently, the Fit for 55 Package included a proposal for an EU CBAM. For
the sectors covered by the CBAM33, the Commission is proposing a phase out of free allocation by 2035,
with a 10% annual reduction.
Moreover, allowances otherwise allocated for free to industry sectors covered by the CBAM are to be used
to increase the size of the Innovation Fund from 450 to 650 million allowances. The Modernisation Fund
would also increase to up to 2.5% of the cap.
The Commission is furthermore proposing to exempt the submission of CO2 allowances for emissions which
are permanently chemically bound in a product. It is devising a Carbon Removal Certification Mechanism
(CRC-M) by 2023. The CRC-M is meant to incentivize the removal of CO2 and the development of Carbon
Capture and Utilization (CCU) technologies.

With respect to the MSR, the Commission has proposed to extend the current parameters until 2030, with
a doubled 24% intake rate of allowances moving into the MSR until then. The change of the intake rate
mechanism to mitigate threshold effects is applicable when the total number of allowances in circulation is
close to the upper threshold of 833 million but below 1096 million. In addition, the proposal calls for a
cancellation (invalidation of allowances) when the allowances in the MSR are above a threshold of 400
million, instead of above the total number of allowances auctioned during the previous year. Additionally,
the MSR will now include the supply and demand from aviation and maritime transport sectors.
As part of the Fit for 55 package, the Commission proposed amendments to the EU ETS Directive with
regards to the contribution of aviation to the EU emission reduction target. The Commission foresees a
progressive phase-out of the free allowances distributed to aircraft operators from 2024 to 2026 (by 25%,
50% and 75% respectively) and a complete phase-out from 2027 onwards.
The Commission also proposes to apply the same LRF as for stationary installations (4.2% instead of 2.2%)
and to rebase the total number of allowances on active aircraft operators in 2023.
The scope of the EU ETS would remain unchanged, i.e., it would cover intra-EEA flights in addition to flights
from the UK and Switzerland. These flights would be exempted from the Carbon Offsetting and Reduction
Scheme for International Aviation (CORSIA)34, whose voluntary phase began in 2021.
One of the most controversial points coming from the Commission proposal to revise the EU ETS is the
potential extension of carbon pricing to new sectors, with a particular focus on maritime, road transport
and buildings.
EU maritime transport CO2 emissions currently account for around 4% of the EU’s CO2 emissions35. For the
maritime sector, the Commission is proposing that CO2 emissions from large EU ships (above 5000 gross
tonnages36) be covered under the current EU ETS starting with a phase-in period37.
EU road transport and building emissions currently account for 30% of the EU’s GHG emissions. For the road
transport and building sector, the Commission is proposing upstream emissions to be covered under an
independent ETS starting in 2026 with a 5.15% LRF.
In contrast, the outlook for the extension to road transport and buildings is still less certain and the decision
will depend on the negotiations between the European Parliament and Council. Such an ETS extension
would almost double the ETS GHG emissions coverage, which would pass from 45% to around 80%.

4.2.1. Brexit implications for the EU ETS
The UK ETS was put in place starting in 2021, as part of the EU-UK trade and cooperation agreement. The
practical implications of Brexit for the EU ETS mainly concern the aviation sector due to the split between
the EU and UK ETS registries. Since flights departing from the UK to the EEA fall under the scope of the
EU ETS after Brexit (see Chapter 4.1.1), all aircraft operators previously administered by the UK needed to
migrate to a participating state under the EU ETS in 2021.

45% for 2024, 70% for 2025, and 100% for 2026 and after.
